SAMUEL CHANDLER AND JOSIAH CHANDLER, OF WESTMINSTER, ENGLAND, ASSIGNORS TO LIVING LETTERS LIMITED, OF WESTMINSTER, LONDON COUNTY, ENGLAND.

DEVICE FOR ADVERTISING OR SPECTACULAR EXHIBITIONS.

To all whom it may concern:

Be it known that we, SAMUEL CHANDLER and .TosIAH CHAN LER, both subjects of the King of Great Britain, residing at 39 Victoria street, Westminster, in the county of London, England, gas-engineers, have invented certain new and useful Improvements in D evices for Advertising or Spectacular Exhibition, of which the following isa specification.

This invention relates to devices for advertising or display purposes such as described in the concurrent specification Serial No. 349,875 of 1906 and consists of an automatic arrangement for changing the color of the liquid traversing the glass tubes.

According to the present invention, supply cisterns oi variously colored fluids are connected with the water pump or aspirator of the advertising device by means of pipes fitted with cocks which are arranged to be opened automatically in succession by connecting them by suitable linkage with a float contained in a tank provided with a controllable water supply.

The level of the float may be raised slowly or at any desired rate and the time during which each cock is opened may be correspondingly varied. A siphon is provided in the float tank which operates to empty the tank at a greater or less speed according to adjustment of the bore when the float reaches its higher limiting position.

The invention is illustrated by the accompanying drawings in which Figures 1 and 2 are a plan and sectional elevation of the device. Fig; 3 is a modification of the invention which is more readily applicable to any number of cocks. Figs. 4, 5 and 6 are cross sections of the regulating cocks shown in Figs. 1 and 2; Fig. 7 is a cross section of the regulating cock shown in the modification, Fig. 3; and Fig. 8 shows the supply cisterns in connection with the aspirator and glass tubes forming the display design. I

In Figs. 1 and 2, a, b, are pipes in the side of the tank (1 conducting liquid from the supply cisterns Z to the aspirator or water pump m connecting with the design at and waste tank 0, as shown in Fig. 8, and have at suitable places along their lengths cocks a b whose slits are so arranged that when one is opened the other is 45 closed. The float 0 contained in the tank dis connected to the plugs of the cocks by means of levers a b Crossbars e e in the tank serve to limit the rise and fall of the float. The water is admitted to the tank by means of the delivery pipe f and can be regulated by the cock 50 f. When the tank is full or filled to a desired point, it empties itself by means of the siphon g, the rate of emptying being determined by the bore of the siphon. When the float c is in its lowest position against the stop e the cock a is open while the cock 6 is shut. As

the float rises the cook a is gradually turned off until when the float is in a central position between the two limiting bars, both the cocks a and b are off as illustrated in Figs. 4, 5 and 6. As the float rises still further the cock I) is now gradually opened and in the highest limiting position of the float the cock b is fully open. As the float c descends the operations are reversed until on reachingonce again its lowest limiting position the cock a is again fully open.

In the modified form shown in Fig. 3, which is more readily applicable to any great number of various colored liquids, the float c is kept upright by guides h h. Along the stem of the float c are suitable spaced pegs 'i which engage in slots j formed in the disks or arms 70, attached to the plugs of the cocks a. The tank is filled and emptied in the same manner as in the construction of Figs 1 and 2. As the float c rises with the water the pegs i on the float stem engage the disks thus turning the various cocks on or off in any desired sequence according as the ports in the cooks or their casings are relatively arranged as shown in Fig. 7. The limiting positions of the float may be determined either by the length'of the radial slit in the disks or by means of the guides h h.

Having thus described the nature of our said invention and the best means we know of carrying the same into practical effect we claim:

1. In devices for advertising, spectacular, or similar purposes, such as herein described, a device for varying the color of the liquid supplied to the design comprising a plurality of cisterns containing liquids of different colors, cocks controlling the supply of said liquids to said design and means for automatically operating said cocks in succession, substantially as described.

2. In devices for advertising, spectacular, or similar purposes such as herein described, a device for varying the color of the liquid supplied to the design, comprising a plurality of cisterns containing liquids of dilferent colors, cocks controlling the supply of said liquids to said design, a tank with a constant inflow of liquid, a float in said tank arranged to operate said cocks in succession, and means for emptying said tank automatically substantially as described.

3. In devices for advertising, spectacular or similar purposes such as herein described, a device for varying the color of the liquid supplied to the design, comprising a plurality of cisterns containing liquids of difierent colors, cocks controlling the supply'of said liquids to said design,

a tank With a constant inflow of liquid, a float in said tank arranged to operate said cocks in succession, and a siphon operating to' empty said tank automatically, substantially as described.

In testimony whereof We have signed-our names to this specification in the presence of two subscribing witnesses.
